"Everyone I worked with was friendly, polite and knowledgeable. Despite the fact that they were removing and adding insulation, there was no debris because they were so careful to keep my home clean. The best part was that the temperature in my son's room increased by six degrees in a matter of hours."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."
Owens Corning ProPink R-49 Blown-In Insulation. Our most popular product
These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"We had Xanvria remove the old insulation in our attic, air seal the attic, and install new R-49 batts. They did a really good job, were professional, and explained what they were doing along the way. Everything came out clean and we?re very happy with the work. I would definitely recommend them."

Drywall Insulation questions, answered by experts

Yes, it matters which side of drywall you use. One side is smooth, and the other is rough. The smooth side should be facing outward, toward the room, while the rough side should be hidden and facing the studs and framing of the house. The smooth side will be easier to apply tape, joint compound, and, later, paint to.

Although they have similar applications, spackle and joint compound are not the same. Their primary differences lie in their composition, consistency, and ideal use cases.

Spackle is composed of gypsum and binding agents, making it thicker than joint compound. It dries quickly and is easy to sand, which makes it ideal for small wall repair projects like filling nail holes or patching minor damage.

Joint compound, also known as drywall mud, consists of limestone and gypsum. It is primarily used for large-scale projects, such as taping and finishing the seams on newly installed drywall. It tends to shrink more than spackle and can be more difficult to spread.

While both products can be used to fill small depressions and cracks, spackle cannot replace joint compound for taping and mudding new drywall. Conversely, you can often use joint compound for small patching jobs typically done with spackle.

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.

Yes, cabinets are installed over drywall. The drywall must be in good condition, and you must ensure that the wall can handle the weight of the cabinets. Secure the cabinets to studs and use proper anchoring devices, like toggle bolts.
